Why do you need a longer brake line? I just put some risers on mine (about 1.5") and there's plenty of brake line slack. The clutch and choke cables took a little re-arranging to work, but all is well now.

Now I need to look up the choke cable spec and re-adjust it. I just eye-balled it so I could ride into town yesterday morning.

PO put a stainless line on and from all the pics I see it looks to be shorter then OE. 2" of rise is gonna be pushing it. Plus the plastic that covers the line is cracked and broken in a few places, looks like crapola.
